"Teeth whitening gimmicks"

[Dianah194]

"Teeth Whitening" products sold on the internet, not all of the products reviewed actually whiten your teeth! they are all marketed as teeth whiteners, some are high priced gimmicks that range any where from $10 to $1000! Some teeth whitening products do actually work! The problems is cutting through the hype to find out which ones are real and work, which ones are real and kinda work, and which ones are just overpriced gimmicks!

I hear they don't work on crowns... I have one right in the front of my mouth and I would love to try one of those products, but would have to have one discolored dark tooth right in front! I wonder if there are any that work on crowns...
